Three-Layer Grating With the Enhanced Efficiency and Angular Bandwidth

We theoretically and numerically analyze and design a three-layer rectangular-groove dielectric grating based on modal design and rigorous numerical calculation. This three-layer grating device can only diffract the transverse electric (TE)- or transverse magnetic (TM)-polarized plane light in the f...
